This analysis quantifies relationships between SPCC 1.0 Refined Smoothed Roadway Segments and households with no access to vehicles as identified in the 2018 Census American Community Survey (ACS).
The following map presents all roadway segments in the SPCC 1.0 Refined Smoothed dataset, symbolized based on the quantile ranking of zero vehicle households per acre per Census block group that the roadway traverses. Zero vehicle household density was calculated by generating four quantiles across the entire D4 study area in addition to one classification for block groups where there is no data.
The following table and charts present the absolute and relative presence of each of the five zero vehicle household quantile classifications for each SPCC 1.0 Refined Smoothed classification. Numbers are presented as either linear feet (absolute) or portion of total linear feet.
